Abstract: 866,427. Protective cut-out arrangements. REYROLLE & CO. Ltd., A. Aug. 15, 1957 [May 17, 1956], No. 15391/56. Class 38 (5). A protective relay arrangement operative in accordance with a comparison of two A.C. sources comprises a junction transistor A having an earthed base A<SP>1</SP>, means for applying to the collector circuit of the transistor a unidirectional operating current derived from one or both sources, means for applying to the emitter circuit of the transistor a unidirectional restraining current derived from one or both sources, and a relay D energized from the output voltage between the collector A<SP>2</SP> and the base A<SP>1</SP> of the transistor. It is stated that with a junction transistor, so connected, for a given value of input emitter current, the output collector voltage remains practically zero for all values of input collector current less than a critical value at which the output voltage increases suddenly to the value determined by a voltage limiting device E. The relay D may be connected as shown for direct energization from the output voltage, or alternatively, the relay may be energized through a second transistor connected in series with the relay and acting as an amplifier. This second transistor may receive its power supply from one of the A.C. sources or from an auxiliary supply, Figs. 2 and 3 (not shown). Fig. 4 shows the arrangement in use as an impedance relay device, the current applied to the emitter AS being derived from a voltage transformer J and that applied to the collector A<SP>2</SP> being derived from a current transformer K. By the use of mixing transformers to enable either or both the unidirectional currents to be derived from both the current and voltage transformers, the arrangement may provide a directional relay device, Fig. 5 (not shown), an ohm relay device, Fig. 6 (not shown), a mho relay device, Fig. 7 (not shown), or a polarized mho relay device. In the last case, the unidirectional currents would include a polarizing component derived only from the voltage transformer J, Fig. 8 (not shown), or a polarizing component derived from the voltage transformer J and a voltage transformer associated with another phase of the protected circuit, Fig. 9 (not shown).

Abstract: 966,680. Semi-conductor devices; capacitors. SIEMENS & HALSKE A.G. April 28, 1961 [April 29, 1960], No. 15453/61. Headings H1K and H1M. A barrier layer capacitor comprises a ceramic dielectric, interposed between two metal electrodes, consisting of an interior portion containing generally distributed donor impurities and two barrier layers each interposed between the interior portion and a respective one of the electrodes, and each containing spatially localized donor impurities. Preferably the latter impurities are located at the interfaces of the ceramic grains in the barrier layers. In an example, a ceramic is formed by sintering BaTiO 3  grains of grain size c. 2Á having an interfacial layer comprising excess TiO 2  either by adding TiO 2  or, preferably, by washing away BaO. The ceramic is reduced at a high temperature in H 2  to produce donor impurities in the grains and in the interfacial layers; then it is oxidized at 750-850‹ C. in an atmosphere containing O 2  so that the grains in an external layer 1b are partly or wholly reoxidized while the impurity concentration necessary for the barrier layer function is substantially maintained at the grain interfaces. The interior la remains strongly N-type. Electrodes 2 are metallized on the exterior layer 1b and connected to leads 3. Alternatively, the oxidation process may be carried out simultaneously with the metallizing step.

[Class 110 (iii)] The exhaust of a main gas turbine 8 drives an auxiliary turbine 10 coupled to a pre-compressor 2 which supplies air to a main compressor 4. The main turbine exhaust is used in a heat-exchanger 6 to pre-heat the compressed air on its way to a combustion chamber 7. The power of the whole set can be varied by varying the speed of the auxiliary set 2, 10 and this can be done by cutting out one or more end stages of the main turbine as by a valve 15. If the auxiliary set is coupled to a dynamo-electric machine 12, the latter may be coupled through a suitable regulator 51 with the main generator 20 and so be used to vary the speed of the auxiliary set. A valve 16 may open the inlet of the turbine 10 to atmosphere. An air-cooler 13 may be provided between the compressors 2, 4. The machine 12 may be used as a motor to start the plant and, when a starting combustion chamber 14 is provided, the auxiliary set may be used for starting. For these purposes a gear and clutch 21 are provided. The turbine 10 may be driven by gases taken from an intermediate stage of the turbine 8.
